Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The investigators propose a technique using cone beam CT perfusion (CBCTP) imaging with an acetazolamide challenge as a potential diagnostic tool to detect a defect in cerebral autoregulation at a time when it has not yet caused clinically apparent signs or symptoms. 30 participants will be enrolled at the University of Wisconsin - Madison and can expect to be on study for about 2 weeks.
